ecosystem : the complex of a community of organisms and its environment functioning as an ecological unit — Webster
Ecosystem is a community made up of living organisms and nonliving components such as air, water, and mineral soil. Ecosystems can be studied in two different ways. They can be thought of as interdependent collections of plants and animals, or as structured systems and communities governed by general rules. The living (biotic) and non-living (abiotic) components interact through nutrient cycles and energy flows. Ecosystems include interactions among organisms, and between organisms and their environment. Ecosystems can be of any size but each ecosystem has a specific, limited space. — Wikipedia
Biome is a community of plants and animals that have common characteristics for the environment they exist in. They can be found over a range of continents. Biomes are distinct biological communities that have formed in response to a shared physical climate. “Biome” is a broader term than “habitat”; any biome can comprise a variety of habitats.
A ‘biota’ is the total collection of organisms of a geographic region or a time period, from local geographic scales and instantaneous temporal scales all the way up to whole-planet and whole-timescale spatiotemporal scales. The biotas of the Earth make up the biosphere. — Wikipedia
Ecology is the branch of biology which studies the interactions among organisms and their environment. Objects of study include interactions of organisms with each other and with abiotic components of their environment. Topics of interest include the biodiversity, distribution, biomass, and populations of organisms, as well as cooperation and competition within and between species. Ecosystems are dynamically interacting systems of organisms, the communities they make up, and the non-living components of their environment. Ecosystem processes, such as primary production, pedogenesis, nutrient cycling, and niche construction, regulate the flux of energy and matter through an environment. These processes are sustained by organisms with specific life history traits. — Wikipedia

Predator-prey interaction study reveals more food...
on September 30, 2020 at 12:51 pm
Decades of data allow researchers to look at predator-prey interactions in a different way: among multiple species throughout the water column. They have developed an unusually rich picture of who is eating whom off the Northeastern United States.
Marine biodiversity reshuffles under warmer and...

Climate warming will alter marine community compositions as species are expected to shift poleward, significantly impacting the Arctic marine ecosystem.
Disastrous duo: Heatwaves and droughts
on September 28, 2020 at 7:29 pm
Simultaneous heatwaves and droughts are becoming increasingly common in western parts of the Unites States, according to a new study. Periods of dry and hot weather, which can make wildfires more likely, are becoming larger, more intense, and more frequent because of climate change.

A new study found the spread of ghost forests across a coastal region of North Carolina may have implications for global warming.
Natural capital a missing piece in climate policy
on September 28, 2020 at 4:51 pm
Clean air, clean water and a functioning ecosystem are considered priceless. Yet accounting for the economic value of nature has large implications for climate policy, a new study shows.

The Arctic hasn't been this warm for 3 million...
on September 30, 2020 at 5:00 pm
Every year, sea ice cover in the Arctic Ocean shrinks to a low point in mid-September. This year it measures just 1.44 million square miles (3.74 million square kilometers) – the second-lowest value in the 42 years since satellites began taking measurements. The ice today covers only 50% of the area it covered 40 years ago in late summer.

The environment in the Cordell Bank National Marine Sanctuary off the coast of San Francisco is not a refuge from the noise generated by ship traffic, the first underwater marine acoustic study of the region has shown.
How will the ocean carbon cycle evolve in the...
on September 29, 2020 at 2:00 pm
The global ocean covers 70 percent of the planet and is essential to humanity's survival, providing food, sustaining livelihoods, and capturing and storing huge amounts of carbon dioxide from the atmosphere. A key scientific question for oceanographers and climate scientists is just how much CO2 can the ocean keep absorbing as the planet warms? This is also a key question for society and for decision-makers working to stem climate change.
